Abstract


The research work deals with Detailed modelling of permanent magnet synchronous motor for electrical drives. In this paper we have discussed about mathematical modelling of PMSM for Electrical Forklifts designing aspects of dynamic model of PMSM Block of the Main model. Permanent magnets to replace the electromagnetic pole with windings requiring a less electric energy supply source resulted in compact dc machines. Likewise in synchronous machines, the conventional electromagnetic field poles in the rotor are replaced by the PM poles and by doing so the slip rings and brush assembly are dispensed. With the advent power semiconductor devices the replacement of the mechanical commutator with an electronic commutator in the form of an inverter was achieved. These two developments contributed to the development of PMSMs and Brushless dc machines. Due to many applications of PMSM like sensor less speed control, appropriate position control, Servo motor, etc. Mathematical modelling of permanent Magnet synchronous motor is carried out and simulated using MATLAB. The most important features of PMSM is its high efficiency given with the ratio of input power after deduction of loss to the input power. There is no field current or rotor current in the PMSM.
